Allow manual input of daily kcal adjustment and macronutrient distribution

First of all, thanks for the amazing, free and open source app. I have ditched all others in favor of OpenNutriTracker.

My suggestion is this: In the calculations option, using manual values for each of the options would make personal goals easier to configure. The way the app works now, each macronutrient slider affects the others, which makes it hard to set certain macro percentages.

Agreed, I've done extensive math and have setup targets that I like, I've used the same target with every nutrition app that I've used. Forcing me to use percentages configured by sliders makes it impossible for me to use this one unfortunately.

There's a couple of issues with this at the moment:

• Only using sliders makes it extremely difficult to set the right value. I tried to set -400 kcal and simply could not. I'd land on -410, or -380, then lift my finger up just the slightest bit and suddenly I'd be at -450.
• Since the sliders only show percentages and don't show real values, I have to manually calculate the correct percentage from the raw numbers and I'm simply not willing to do that.

Please make it possible to simply set hard coded target values.
